During the second day of the conference, three plenary sessions took place: enabling environment and financing sustainable energy for all in SIDS; future steps on promoting sustainable energy for all in SIDS; and feasibility studies on renewable energy options for the Caribbean and replicability for other islands.

In closing the high-level conference in early afternoon, representatives of governments adopted the Barbados Declaration on Achieving Sustainable Energy for All in SIDS, which recognizes challenges and opportunities for SIDS in achieving sustainable energy. The Barbados Declaration also welcomes the voluntary commitments by 18 states to promote transformational activities in the areas of renewable energy, energy efficiency, energy access, and low-carbon development. The document further welcomes existing sustainable energy initiatives such as SIDS DOCK, a collective institutional mechanism to assist SIDS in energy transformation, and others. On the upcoming Rio+20 conference, the Barbados Declaration that reiterates the outcomes of the meeting must be ambitious and supports convening the Third Global Conference on Sustainable Development of SIDS in 2014 as a tangible outcome on SIDS.

In the late afternoon, the knowledge fair opened its work with a number of presentations by SIDS, including the Bahamas, Jamaica, and the Solomon Islands, which focused on national sustainable energy initiatives. Business representatives from GE Energy, Toshiba, Aquaver and others also presented on private sector energy cooperation with small island states.
